its running good but its way too out of control. If I were you is start adjusting your cg to compensate for the hopping and try and get the prop to stay in the water more it may settle down the whole boat.

@egned thanks :)

@namba i was thinking the same thing, i run mu batts up the from i was thinking of having one up the front and one up the back then run a lifter prop to make the front more stable. what do you think of that idea?

At those speeds it's hard to keep it on the water. I added 7oz (about 200 grams) up front to settle it down. Also set the strut at 23mm and neutral. I ran a stock motor, 120 esc, and a M445.

try just moving the bats as far forward as you can. And then try a lifting prop with the bats as far forward and see what it does.

the batt are right up the front i,ll just adjust the strut then put a lifting prop on it

lifting prop just wont help the boat at all they require props with minimal lift , they are a very lightly built boat be very carefull with it other wise you will end up binning the boat in bits. you will be horrified about the glass work in them its absolutely crap

[borgie]

ok thanks

[wayne middlemiss]

having said all of that the boat has loads of potential as the design basis is there but they are mass produced in china at cheapest price.
my own boat i have done molds from it to get a more quality boat heavier ,weight does nt hurt hydro's providing its not over done.
will be using stock set up in one and the othe will be neu 1515 1.5y 2200kv power will be crazy fast providing i cant get it all to work the way it should . have fun.

thanks for your advise
